Create TV-Based Chunks - Parse Error

I have followed the instructions from this page http://wiki.modxcms.com/index.php/Create_TV-Based_Chunks but it doesn’t seem to work. It says:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting ’)’ in C:\xampp\htdocs\pearson_whiffin\manager\includes\tmplvars.commands.inc.php(61) : eval()’d code on line 1

I’m running the following:

MODx version 1.0.5
XAMPP for Linux 1.7.4
Apache 2.2.17
MySQL 5.5.8
PHP 5.3.5

Any help would be much appreciated as I have no knowledge of PHP.

Thanks
